The Who's Roger Daltrey, Aerosmith's Steven Tyler, Cheap Trick's Robin Zander To Tour With Trans Siberian Orchestra

The Who's Roger Daltrey and Aerosmith's Steven Tyler have given the Trans -Siberian Orchestra a Christmas boost by signing up to join the symphonic rockers on tour in November and December.

The two will join Cheap Trick frontman Robin Zander as the guest stars on the orchestra's annual U.S. holiday tour, which begins on November 1st.

Also, the Trans-Siberian Orchestra has announced the upcoming release of its hugely anticipated new album. "Night Castle" will arrive in stores and all digital retailers on October 27th.

Years in the making, "Night Castle" is without question TSO's most ambitious and adventurous work to date. Founder Paul O'Neill and crew have created 26 songs that run the gamut from hard rock to classical, taking the listener on a journey through different points of history.

"Night Castle" details the triumphs and follies of man but is ultimately an epic story of transformation and love. The two-CD set will be released at a special low price, and will include a unique 68-page booklet, featuring story, lyrics, and full-color illustrations by legendary artist Greg Hildebrandt.

"Obviously our fans have been unbelievably patient," O'Neill says. "This was supposed to come out a few years ago. But we were dedicated to making something really special, and the longer it took, the more pressure we felt to give people the best possible piece of art we could.

"These are hard times," he adds, explaining the lower price, "and we're trying to do what we can to make them better. We believe in value with Trans-Siberian Orchestra; everything we do – the shows, the albums, the souvenirs – are over-the-top productions with a lot of stuff for people to see and hear and feel, and we do that for as inexpensive a price as we can."

"Night Castle" will be preceded by the first single, "Nutrocker," which ships to multi-format radio outlets nationwide later this month. The track sees TSO paying homage to one of their greatest influences, Emerson, Lake & Palmer, and features rock icon Greg Lake on bass.
